Have you ever witnessed any crimes or accidents ?   I don't quite remember . Why did you ask that ?   I was taking a walk in the park early this morning when suddenly I heard someone calling " help " . I rushed over and saw a man beating a woman .   Oh , my . What did you do ?   I guess I was stunned for a moment , then I quickly ran away to get help .   Did you call the police ?   Yes . Fortunately , I had my cell with me this morning . I called the police as I was running to get people to come to help .
